Research methods that equipment - mathematical modeling and analysis, experimental research is elaborated and created samples amplifier and transmitter. Industrial - preparedness and test signals are made generators, spectrum analyzers, polarization attenuator, izmiritel microwave power PC. Results: A new method for reducing intermodulation distortion in the output amplifier, the output power of the transmitter short centimeter wavelengths. Winning obtained by the transition to the next channel Zavada (ACPL) in the proposed transmitter with injection energii harmonic signal of about 25 dB. The proposed new, polnustyu planar structures, amplifiers with spatial adding capacity and its components built on the N = 2,3,4 active elements. Developed a 12-channel transmitter range 12GGts to serve on the base station of broadband access. For measuring transmitter designed and manufactured special equipment. Theoretically solved a number of problems in the new field of system distortion compensation scho made non-linear element.
